<p class="MsoNormal">Hi folks,<o:p></o:p></p>
<p class="MsoNormal">We are using a GDAL trunk snapshot from February 2011 (so 1.9dev ?) on a Windows 7 environment. We have a Kakadu JPEG-2000 license and can successfully make NITF files with JPEG-2000 compression. The compression appears to be the default
QUALITY=20 because the files are consistently reduced in size by 80% with high quality.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But is it possible to make *<b>lossless</b>* JP2KAK within NITF ? Using the GeoJP2 driver, we can do lossless using the QUALITY=100 creation option, but the same option on the NITF attempt is ignored, resulting in the same 80%-reduction-with-high-quality
version. I’m guessing this is due to the driver-within-driver issue (JP2KAK within NITF) so the NITF driver doesn’t know what to do with the QUALITY=100 request.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there any ‘gdal_translate’ syntax that will currently achieve the NITF-with-JP2KAK-lossless goal ?<o:p></o:p></p>
